Optical Stretcher of Biological Cells Using Sub-Nanometer Optical Tweezers Generated by an Add/Drop Microring Resonator System

Abstract

The design system consists of a nonlinear modified add/drop Microring Resonators (MRR) to build up optical tweezers in the form of potential wells is presented. The optical tweezers can be used for sub-nanometer objects trapping to form an optical stretcher used to deform the biological cells. The fabricated material used is InGaAsP/InP, which provide the required output signals. The optical tweezers can be formed by the dark soliton pulses and can be tuned and amplified using the Gaussian laser beam input. The optical dark soliton pulses with the central wavelengths range 1.4 to 1.55-m are fed into the system, collide with the input Gaussian laser beam at the add port and finally the optical tweezers with bandwidth of 4, 12 and 18 nm could be generated and used to trap sub-nanometer objects using a molecular buffer system. Interacting the tweezers holding the subnanometer objects with human tissue, influence the cellular surface of the cells by the generated forces. Therefore an optical stretcher can be formed to deform the biological cells of human tissue using optical tweezers.
